PADLOCK.

SPECIFICATION forming part of Letters Patent No. 496,698, dated May 2, 1893.

Application filed September 19, 1892. Serial No. 446,252. (No model.)

To all whom it may concern.-

Be it known that I, JAooB S. PEAGOCK, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain Improvements in Padlocks, of'which the following is a specification.

This invention relates to improvements in that class of padlocks in which one end of a U-shaped hasp or shackle is pivoted in the case, and consists in the construction and combination of the various parts, as hereinafter fully described and then specifically pointed out in the claims.

In the accompanying drawings, which form a part of this specification, Figure 1 is a perspective view of the lock, showing the closingplate removed, a portion of the rim or edgeplate cut away and the bolt engaging the swinging end of the shackle. Fig. 2 is an innor face view of the closing plate, shown detached. Fig. 3 is a plan or face view of the lock, the closing plate being removed and the bolt shown engaged with the swinging end of the shackle. Fig. 4 is a view similar to Fig. 1 but showing the bolt in the position occupied by it when disengaged from the shackle, a portion of the spring being cut away. Fig. 5 is a perspective view of the interior of the lock, showing the bolt and spring removed. Fig. 6 is an edge sectional view taken on the line a:w of Fig. 3, showing the spring removed. Fig. 7 is a like view but showing the spring in place. Fig. 8 is a face'view of the lock. Fig. 9 is a plan view of the bolt detached, and Fig. 10 a face view of the key.

Similar letters indicate like parts throughout the several views.

Referring to the details of the several views, A represents the body of the lock, and B the shackle; the rim of the body of the lock and the rim of the shackle forminga circle. Rivetpins are constructed with the body of the case, one of which, a, is located in the body of the case and the other, a, at an upper corner thereof, to which the fast end of the shackle B is attached. As will be observed the case forms one-half of a circle and the shackle, when closed, the other half. The upper or diametrical edge-plate O of the case extends between the openings in which one limb, b, of

the shackle is pivoted and the other or swinging limb, b, is detachably locked.

Inside of the edge-plate 0 there is a rib D formed on the back-plate A of the case. The central portion 01 of the rib D is reduced to form a recess through which there passes a tongue 6 of the locking-bolt E. This tongue 6 is beveled on the left side 6, being the side engaged by the key when forcing the bolt out -of engagement with the shackle. At the end of the reduced portion at of rib D adjoining the fast end of the shackle there is a shoulder (1'. This shoulder is engaged by a shoul der eiof bolt E when said bolt is in engagement with the fast end of the shackle.

In the body of the lock-case there is built a post F, around which is a coiled spring G, one end, g, of which bears against the rear end of bolt E and the other against the reduced end 19 of the swinging limb b of shackle B.

The closing-plate is provided with a hole suitable for the insertion of thekey, and the back-plate of the case has an opening or recess h for the reception of the heel 7c of the key K.

On one side of the space occupied by the key when inserted in the look there is located a postm, having thereon a flange M parallel with the back of the case. This flange M is adapted to engage a notch in the key and the height of post m, in different locks, is so regulated as to afford changes for keys for various locks of the same construction. The sides of the notch k in the key engaging flange M may be so constructed as to engage the tongue e of l0cking=bolt E, or the post 'm with its flange M may be set so far from bolt E as to only permit a notch 7.0 in the key outside of the range of tongue e to engage it. The rear end e of bolt E is curved or beveled so that the pressure of the end g of spring G tends to force the shoulder e of said bolt into engagement with shoulder d of rib D, as the forward end 6 of said bolt E engages a notch 19 in the swinging limb b of shackle B.

Inopening the lock, the ward of the key presses against and turns toward the side e of tongue 6 of bolt E, thus by one movement raising said bolt so as to disengage the shoulder 6 of said bolt from theshoulder d. of 'rib D and retracting the forward end of the same from engagement with the notch b of the swinging limb of the bolt. After the key has disengaged bolt E from the shackle and the wards thereof pass from the tongue 6 of said bolt,'bolt E is again forced beneath the opening through which the swinging end of the shackle enters the case. The front end of the bolt is beveled, as shown ate, to permit it to be forced back by the swinging end of the shackle as it is pushed into the lock.

The construction herein described possesses many advantages over padlocks now in use. The circular form of the lock-case and shackle prevents, as nearly as may be, any effect upon the interior mechanism from blows upon the edge of the lock; the action of the spring on the beveled rear end of the bolt not only holds the said bolt in engagement with the shackle but also holds the shoulder in the same in contact with the shoulder in the rib below said bolt, so that the key must both disengage the bolt from the shackle and separate the shoulders of the bolt and rib.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. In a padlock, the combination, with a case and shackle, of a bolt having the upper edge of its rear end beveled and a shoulder formed on its lower edge, a rib guiding the bolt in its movements and having a shoulder adapted to be engaged in front by the shoulder of the bolt, a spring bearing downward and forward on said bevel at the rear end of the bolt, a spring engaging under the swinging end of the shackle when engaged in the case, and a tongue formed on the bolt and having its front edge beveled and adapted to be engaged by the key, substantially as and for the purpose specified.

2. In a padlock, the combination, with a case and shackle, of a rib having a recess formed therein, a bolt located bet-ween the top of the case and the rib and having the upper edge of its rear end beveled, a shoulder formed on the lower edge of the bolt and constructed to engage the shoulder forming the rear end of said recess, a tongue on the bolt extending through the recess in the rib and having its front edge beveled and adapted to be engaged by the key, a post located below the rib, and a spring held in place by the post and having one end engaging the beveled rear end of the bolt and the other engaging under the swinging end of the shackle, substantially as and for the purpose specified.
